Use Subject Alternative Names (SANs) to Secure Your Entire EnvironmentUnified communications (UC) certificates (also called SAN certificates) use Subject Alternative Names to secure up to 4 domains, sites, and subdomains with one certificate. For example, with a UC certificate you can secure www.example.com, www.example2.com, www.example3.net, mail.example.net, dev.example2.com, etc. This makes UC certificates perfect for Exchange/OCS environments or any environment where you need to secure multiple names across different domains. |
